Just in case you didn’t get it from the title, Metroid Prime Trilogy combines the GameCube and Wii’s best-selling Metroid games – Prime, Prime 2: Echoes and Prime 3: Corruption – on one disc. But this release isn’t just a quick cash-in. A number of upgrades – visual and control-wise – have been included to bring older fans back to the Prime games, while giving newer fans enough to be excited about once the pack is released on August 24.
